Note 1. When not using the phase detection terminals, fit the jumpers across RX-R, SX-S and TX-T. If the jumpers remain removed, the
FR-RC-(H) will not operate.
2. When using servo amplifiers of 5kW and 7kW, always remove the lead of built-in regenerative resistor connected to P terminal
and C terminal.
3. For sink input-output interface. Refer to section 4.8.3 for source input-output interface.
4. P and P are connected by default.

5. The diagram is for when outputting the malfunction (ALM) is enabled by changing the parameter. If disabling malfunction (ALM)
output, configure the power supply circuit which switches off the magnetic contactor after detection of alarm occurrence on the
controller side.
6. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class in 400V class servo amplifiers.
7. Refer to section 1.2 for the power supply specification.
8. Configure the circuit which shuts off main circuit power with external sequence at forced stop (EMG) off.
9. For the selection of the power factor improving AC reactor, refer to "Power Regeneration Converter FR-RC Instruction Manual
(IB(NA)66330)".
